Product Details American-Made New and Improved Optical Design Edmund Designed and Engineered Clear Base Admits Light High Power, Wide Field Transparent Base Magnifiers are excellent for determining paper quality and ink absorption. They are ideal for proofreaders. The transparent acrylic base rests directly on work for clear, close-up examinations. Transparent Base Magnifiers have a base that admits light to the subject under view. 12X and 9X are Kellner-type, color-corrected, three-element lens systems. Twist focus with lock-ring for permanent setting. Contact reticle adapter ring on base accepts all 27mm diameter reticles. Since power increases as field of view decreases, the full reticle pattern of some crowded reticles will not be visible using the 12X comparator. Nylon case #36-286 is sold separately.
